Electroless Nickel-plated Steel versus Stainless Steel: Case Studies

This paper highlights two case studies of manufacturers that have replaced, or done studies to replace, stainless steel with electroless nickel-plated mild steel. In both cases, cost savings could be realized while maintaining or improving product quality.

Methods and Formulas to Determine Internal Deposit Stress in Applied Metallic Coatings

Internal stress exists in electroplated and chemically applied metallic coatings. This paper reviews the test procedures for measuring deposit stress and the formulas used to calculate stress values. Many formulas used require modification to obtain actual internal stress values. Errors in this regard are examined and common mistakes are explained.

A Comparative Study of Gamma-Phase Zinc-Nickel Deposits Electroplated from Various Alkaline and Acid Systems

Sacrificial anodic coatings, specifically zinc deposits, have provided corrosion protection to components and parts across many industries, with an increasing demand in the automotive and industrial sectors. Today, typical sacrificial applications for fasteners, fuel systems, braking systems and drive assemblies require higher corrosion performance from anodic coatings. Electrochemical alloys can be designed to provide the highest corrosion potentials to meet these increased demands.

Toxic Heavy Metal Free Stabilized Electroless Nickel Processes

This paper will introduce an advanced alternative to Pb and Cd-free electroless nickel processes, which is completely free of toxic heavy metal (THM) stabilizers. The process and deposit characteristics will be discussed and compared to the traditionally Pb stabilized electroless nickel.
